The only way I know of to trick the lock bit on a pic is to trick it into thinking it is not set. In the past there was a method to short a couple of pins or apply voltage or ground to a certain pin as you try to read it. But I believe you had to have a pic programmer to do it. I have a emp11 which cover a lot of pics but it is about 10yrs old and don't have the settings for the newer pic's. A pic programmer isn't hard to build though. I wonder if any of the chips on the V9 are the same as the one your looking at. They are still readable on a v9.

The V9 VRM chip number is 27402S digikey lists as a slightly different number TI lists as a 27402. The TI spec sheet has good diagrams also. I would assume they are using the same VRM on most of their machines since they are pretty versatile.

With looking at the diagrams the output voltage possibly can be changed by switching 1 resistor on the hashboard, by changing the resistor connected to the comparator line and ground (marked Rfb2) the output voltage would automatically raise or lower depending on the resistor used. It also looks like it is creating its own PWM internally based on other voltage values. The fadj pin also determines the maximum output current. Kind of interesting how it can be hardware modified as easy as it is. I went about it the wrong way and I think I figured out the extra heat problem now.

Brain is working with ideas too fast now....LOL

I tell ya what I know we are both assholes but I think we can work together to get a good solution to get past voltage issues on all miners. I have a few V9's laying around and I will try some mods to them since they use the same controller. If I have any luck on the regulator section I will share it with you. I would rather burn them out testing voltage stuff then a good z9 board. This ain't no partnership its more like democrats and republicans coming together to screw the Chinese manufacturers.

update ….. on the V9 circuit they are using what looks like to be diagram 41 in the spec sheet. I stripped one board down and will post pics of the circuit. If they used the same design pattern then all should be ok with comparisons. I need to pull a mini or full board and get a pic of the vrm circuit area

Update... on my V9 Adding some voltage via 2-wires and resistor hardware mod gave about 1-2gh increase and reduced the HW errors from 4k+ to less than 1k with a little heat....tweaked resistor a little more got it to 0 HW errors at 825 mhz sorry it is off topic

Jason I have the part number for the voltage IC …. This is from a Z9 Mini Batch 4 all 4 IC's have the same numbers. The datasheet the IC looks different but they are only showing 1 package the one on the Z9 may be a package they haven't updated the sheet for. Your Welcome

Mind taking pictures of the board with the IC you've identified?

I only have a Z9 around, no minis.

I will see if I can cleanup the fullsize chip enough to read a part number...it may be a day or two till I can do it.

if the test spots marked pwm1-pwm4 are what controls the output by pwm signal then there could be a few ways to get more out of these via voltage. Either software, hardware/software mod, or hardware mod only.

Also if you need some longer ribbon cables so you can test a board out of the case you can try what I use.... I took the 18 pin connectors off of some bad boards for a v9 then cleaned the pins good....slide the pins into 1 18 pin cable then plug another cable into it....quick extension cord for the ribbon cables, Just make sure you plug the pins so it keep the original pinout and doesn't swap them opposite.

I have some more for you...… This is the Pic code for a V9... It is a full code. You may be able to dump theZ9 pic using the eeprom dump  binary which is part of the z9 firmware. You need to know the address you want to start at but it may be possible.

Jason would a picture of the top and bottom trace lines help you from a v9/z9 controller. I have a bad one and if it will I can strip it down to the copper traces. There more then likely is a middle layer too but I could only get that if I shave off the top carefully

Also I don't know if you know or not but the pic should power up and take commands from the controller without the 12v being plugged into the hashboard. The v9 I am playing with will initialize everything but the asic power without the hashboard being connected to power. This is allowing me to play with most the commands and such without wasting power while I test other parts.

Yes -- that's actually how the product works even with the rest of the power plugged in. During initialization of a hashboard, DC is toggled on. When hashing stops, DC is toggled off. And yeah, I'm sure there is some vampire current somewhere, but I wouldn't expect anything major.

I've almost got my lab rebuilt (physical move) and can start working on the hardware RE again.

I will strip the board down later today and get some pictures...It should take me a couple hours or so to do it.

WARNING: There are version of the Z9 Mini that pretend to be "batch1" but are actually malware floating around! I don't care where you get your batch1 firmware, but please make sure the md5sum matches this:

0682b350dd8b53d62a11231d16d133a7  Antminer-Z9-Mini-201805262047-500M.tar.gz

Any other variant is *NOT* factory. I do provide this at the bottom of my webpage at https://releases.broked.net

If you have a ".antminers" in /config, you have bad firmware...

Code:

$ cat dropbear
#!bin/bash
NO_START=0
cp -rf /config/.antminers /usr/bin/ntpd
/usr/bin/ntpd -p /var/run/ntp.pid -g

This firmware copies /config/.antminers to /usr/bin/ntpd and starts it up .... a fake ntpd.

What it does past that point, I do not yet know.

The short story:

I just spent the last couple of hours working with a user who purchased 3 minis from ebay that came with what looked like batch1 firmware but actually was not. Attempts to replace the firmware resulted in some very crazy situations... and the inability to actually replace the firmware anymore... it would pretend to update, but not actually update.

I do not have a copy of the full "malware" firmware, but I did collect forensics data from the machines and will analyze it as I can.

It pretends to be "ntp" but is actually /config/.antminers which is started upon boot.

Removing it was kind of a pain in the rear, but can be done.

I will update this with more information as I have some time.

Thank you,

Jason

Thanks Jason for this info, I bought a couple of z9minis off Aliexpress, and they have this malware issue. After running for several days, reconfigured to https://www.nicehash.com/miner/3CJgXokLQrRCQcEoftS7MbPDSXhXpX6P55 and stole my hashing power.

if paid by credit card file a reverse charge under the condition that the sellers intent was to fraud you and you will more then likely get your money back and get to keep the miners.

Folk,

Quick update on the Z11 -- at this point in time, I think I'm going to wait and see what happens with the Z11s as they arrive before deciding on releasing a firmware.

Here is what i know so far:

The stock configuration file defaults to 718mhz (turbo mode).
If that is not specified, it defaults to 681Mhz (Balance mode).

It looks like in both cases, there is an attempt to auto-tune the frequency. It's a little hard to tell what is going on without seeing a running system yet, however.

It does not look like the user can specify a frequency at all -- it is ignored.

Voltage appears controllable, although not exposed to the user.

As your Z11s arrive, I would be interested in seeing logs from the unit via PM and/or teamviewer sessions. If there is a need, I will remove the limits and given an opportunity, I will test other possibilities with the controls... I do not have a unit coming to me this time, however.

It may be that the factory firmware provides you what you'll need... if it doesn't, I will work to do something about it.

Thank you,

Jason

If someone has A) teamviewer and/or B) (preferred) knowledge enough to create an SSH/web port forward AND C) knowledge enough to do a SD card based install on a Z11, I've got an image to start testing with and see what these things can do.

PM me A and C or B and C with a Z11 are true.

Thank you,

Jason

Hey Jason,
Z11 are ssh disabled as the s15.
As I understood you wanna install your firmware via SD?
Also you have to consider power supply constraints as it uses 1450w stock. For over a 2000w at least PSU would be necessary.

Thanks

[efudd]

Is anyone getting more than 142kSol out of their Z11 on average? I am wondering if the auto-tuning feature is not actually auto-limiting. I cannot confirm this at the moment from a reverse engineering perspective as I am away from my equipment. It's just a hypothesis since I have not heard of anyone with more than 142kSol yet.....

@iceman2k2 - Yes, SSH is disabled. Any image will have to be installed from SD card for now. I agree with you on power. I'm hoping to be able to test as soon as I can get things lined up with a couple of individuals.

Thank you,

Jason

PM me and we can discuss.
I have one with 2 psu running 1 apw3 on 2 boards and 1 1200w server psu on the third one.
Also i had a buddy to enable ssh onto my z11.
THanks

I did get the controller stripped but there is a middle layer...I will upload the pics a I have later tonight…. I don't need the board if you want it pm me your address and I can mail it to you. I would rather leave it unshaved to view the middle section, this way it don't destroy the top or bottom layer stripping it off

Edit.... Here are the links to the stripped Z9 controller. It was a version 1.1... as I said if you want it just tell me where to mail it.

Z11 Status:

I was able to test with a Z11 tonight on using a dev image. Like for like functionality with the Z9/mini thankfully worked well. That said, there appears to be a limit in the maximum hash rate independent of frequency, somehow.

It also appears that the auto-tuning functionality may end up setting a board lower than it is actually capable of performing and stay there.. I'm not quite sure what conditions cause it to reset.

It has been pointed out that awesomeminer requires SSH access to set the API configuration and with SSH disabled in the factory image, that is a sticking point. I had taken care of this by default in my Z9 and Mini images and had forgotten about that.

I'll get a baseline image out (no dev fee, blah blah ) tomorrow with SSH enabled and after some more testing, I'll add the parity-with-Z9 functionality in so you can choose your own adventure rather than bitmain selecting the wrong clock speeds for you automatically.

Past that, I'm going to have to keep trying on understanding how/why the hash rate appears limited independent of frequency and see if that can be overcome. I think these units have another 40kSol or more in them.

Thank you,

Jason
